2001 Jaguar S-Type Fuel Pump Location: The Complete Guide to Finding and Replacing It

The bottom line: The fuel pump on a 2001 Jaguar S-Type is located inside the fuel tank, which sits beneath the rear seat on the passenger side. To access it, you need to remove the rear seat cushion, unbolt the access panel, and carefully lift out the fuel pump assembly. A professional replacement typically costs between $410 and $721, depending on your location and engine type, but doing the job yourself can save you hundreds of dollars.

Understanding Your 2001 Jaguar S-Type Fuel Pump

The fuel pump on your 2001 Jaguar S-Type is an in-tank electric pump. It is mounted inside the fuel tank and is part of a larger assembly that includes the fuel level sending unit and the fuel filter. This pump is responsible for delivering fuel from the tank to the engine at the correct pressure. When it fails, the car will struggle to start, lose power during acceleration, or stall unexpectedly .

The pump is not a separate component you can easily swap out on its own in most cases. It comes as a complete fuel pump module assembly. The OEM part number for the 2001 S-Type is XR822164, and it fits both the 3.0L V6 and 4.0L V8 engines .

Exact Location of the Fuel Pump

The fuel pump on the 2001 Jaguar S-Type is located in the fuel tank. The fuel tank itself is positioned under the rear of the vehicle, but the access point to the pump is from inside the cabin.

Here is the step-by-step breakdown of where to find it:

1. Inside the passenger compartment
The fuel pump is accessed through the floor beneath the rear seat. You do not need to drop the fuel tank or get under the car.

2. Under the rear seat cushion
The rear seat cushion on the 2001 S-Type is a simple pull-up design. There are two clips near the front edge of the seat bottom. Firmly pull up on the front of the seat cushion to release the clips, then slide the cushion forward and out.

3. Passenger side floor panel
Once the seat is removed, you will see a metal access panel on the floor, located on the passenger side of the vehicle. This panel is held in place by either bolts or screws, depending on the build date of your car.

4. The fuel pump module
Removing the access panel reveals the top of the fuel pump module. The module sits inside the tank and is secured by a locking ring. You will see the electrical connector and the fuel lines attached to the top of the module.

Tools You Will Need

Before you start the job, gather these tools:

  • Flathead screwdriver (for prying clips)
  • Socket set with extensions (typically 10mm and 8mm sockets)
  • Torx bits (T20 and T25 are common)
  • Fuel line disconnect tool (for quick-disconnect fittings)
  • Pliers
  • Shop rags or towels
  • Safety glasses
  • Fire extinguisher (keep one nearby when working with fuel)
  • Replacement fuel pump assembly (OEM or high-quality aftermarket)

How to Replace the 2001 Jaguar S-Type Fuel Pump

Replacing the fuel pump on your 2001 Jaguar S-Type is a job many DIYers can handle in a weekend. The total cost for a replacement part, if you do it yourself, is typically under $200 for a quality aftermarket pump, compared to $543 for a genuine OEM unit from a dealer .

Here is the process in clear steps:

Step 1: Relieve fuel system pressure
Locate the fuel pump fuse in the passenger compartment fuse box and remove it. Start the engine and let it run until it stalls. Crank the engine for a few seconds afterward to ensure all pressure is gone. Disconnect the negative battery terminal.

Step 2: Remove the rear seat
Pull up on the front edge of the rear seat cushion to release the two clips. Remove the seat cushion entirely.

Step 3: Remove the access panel
Use a Torx bit or socket to remove the screws or bolts holding the metal access panel in place. Set the panel aside.

Step 4: Disconnect the electrical connector
Carefully unplug the electrical connector from the top of the fuel pump module. Some connectors have a locking tab that needs to be pressed before pulling.

Step 5: Disconnect the fuel lines
Use a fuel line disconnect tool to separate the quick-disconnect fittings. Be prepared for a small amount of fuel to spill. Have rags ready.

Step 6: Remove the locking ring
Use a hammer and a flathead screwdriver or a specialized locking ring tool to tap the locking ring counterclockwise until it loosens. Remove the ring by hand.

Step 7: Lift out the fuel pump assembly
Carefully lift the fuel pump assembly straight up out of the tank. The fuel level sender arm is attached to the side, so tilt the assembly as needed to avoid bending it. Place the assembly in a clean container.

Step 8: Install the new pump assembly
Transfer any necessary components from the old assembly to the new one, such as the rubber gasket or the fuel level sender if it is separate. Lower the new assembly into the tank, making sure the fuel level sender arm does not catch on anything. The assembly should sit flat on the tank opening.

Step 9: Secure the locking ring
Place the locking ring back on top of the assembly. Tap it clockwise with a hammer and screwdriver until it is snug. Do not overtighten it.

Step 10: Reconnect everything
Reconnect the fuel lines (push them in until they click), plug in the electrical connector, reinstall the access panel, and put the rear seat back in place.

Step 11: Test the system
Reconnect the battery and install the fuel pump fuse. Turn the ignition to the ON position (do not start the engine) and listen for the fuel pump to prime. It should run for about 2 seconds and then stop. Check for any fuel leaks around the connections. If everything looks good, start the engine.

Common Symptoms of a Failing Fuel Pump

If you are trying to diagnose whether your 2001 Jaguar S-Type needs a fuel pump replacement, look for these signs :

  • Engine struggles to start or cranks for a long time before firing
  • Loss of power during acceleration, especially when going uphill or carrying a load
  • Engine sputters or hesitates at highway speeds
  • Whining noise coming from the rear of the car (the fuel pump is usually quiet when working properly)
  • Engine stalls unexpectedly, particularly at low speeds or after driving for a while
  • Check Engine Light comes on with fuel pressure-related codes
  • The car will not start at all

If you notice any of these symptoms, it is best to address them quickly. Driving with a failing fuel pump can leave you stranded and may damage other components in the fuel system.

How Much Does Replacement Cost?

The cost of a fuel pump replacement on a 2001 Jaguar S-Type varies depending on where you live and whether you choose a dealership, an independent shop, or do it yourself .

Here are real-world examples of what others have paid:

  • 2001 Jaguar S-Type 3.0L V6 (California): $410 to $502
  • 2001 Jaguar S-Type 4.0L V8 (California): $442 to $540
  • 2000 Jaguar S-Type 3.0L V6 (Florida): $309 to $377
  • 2002 Jaguar S-Type 4.0L V8 (Florida): $590 to $721

The national average for a fuel pump replacement across all vehicles is between $611 and $894 . For the Jaguar S-Type, you can expect to pay between $400 and $1,000 at a shop. If you go to a Jaguar dealership, expect to pay closer to the $1,000 mark, especially if they need to replace the entire fuel pump module assembly.

Doing the job yourself saves you the $200 to $700 in labor costs that a shop would charge .

Preventing Future Fuel Pump Problems

Your fuel pump is a wear item, but you can extend its life with a few simple habits :

1. Keep the tank at least one-quarter full
The fuel pump relies on gasoline to stay cool and lubricated. Running the tank low allows the pump to overheat, which accelerates wear. This is the single most important thing you can do to prevent premature failure.

2. Use quality fuel
Fill up at reputable gas stations. Poor-quality fuel often contains water, dirt, and other contaminants that can damage the pump and clog the fuel filter.

3. Replace the fuel filter regularly
A clogged fuel filter forces the pump to work harder. Follow your owner's manual recommendations for fuel filter replacement, typically every 30,000 to 60,000 miles.

4. Listen for changes
Pay attention to the sound your fuel pump makes. A quiet hum is normal. If you hear a loud whine or a change in tone, have the system checked before the pump fails completely.
